Mick Jagger thinks that the Rolling Stones were "sloppy" when they performed in the 1970s, he has revealed.

The frontman was speaking at the premiere of the digitally remastered version of Ladies And Gentlemen ... The Rolling Stones, the 1973 film of Stones concerts.

He said of the footage: "Everyone's very together and on. I can remember the Rolling Stones being very, kind of, lackadaisical, very sloppy band on stage. But this was obviously not the case on this day."

The new version of the film, which made its world premiere on Tuesday in London, shows the band belting out classics like Brown Sugar, You Can't Always Get What You Want and Jumpin' Jack Flash.

None of the current Rolling Stones members who are in the movie - Mick, Keith Richards and Charlie Watts - made it for the premiere. A short interview with Mick, recorded in London about six weeks ago, was played on screen before the film began.

The movie, pieced together from several different concerts played in Texas in 1972, will be shown in cinemas around the world in the coming weeks.
